IPC: G03G15/02
Filed: 1997-11-04
Abstract: PROBLEM TO BE SOLVED: To enable stable electrification even when a roller cleaning member is always made in press contact with an electrifying roller. SOLUTION: In order to reduce the size of a device, even when the roller cleaning member 22 is always made in press contact with the charging roller 9, by defining a surface roughness on the surface butting to the roller cleaning member 22 of the charging roller 9 as >=5 μm and <=30 μm in ten points mean roughness, the roller cleaning member 22 is appropriately finely vibrated at the rotary time of the charging roller 9, therefore depositions can be hardly stuck on the surface of the charging roller 9. Therefore, the jittery image can be prevented from the occurrence, since the stable charge is made possible by restraining variance of the charge potential.

Title: Semiconductor integrated circuit device
Inventor: SUZUKI JUNJI
IPC: H01L27/04
Filed: 1986-12-17
Abstract: PURPOSE:To easily obtain a divided voltage output approximated to a value of divided supply voltage, divided corresponding to a specified resistance voltage division ratio, by making uniform depletion layers corresponding to respective resistance regions connected in series. CONSTITUTION:The voltage impressed upon an N type semiconductor region 16 is halved in an example of halved resistance region. Thus, the inverse bias voltage between a P type resistance region 16 connected to the lower power supply voltage and an N type semiconductor region 8 is halved to reduce a depletion layer 18 similar to another depletion layer 17. Incidentally, when the resistance region is trisected or divided in m equal parts, the voltage concerned is also trisected or divided in equal m parts. Resultantly, when the resistance regions divided in m equal parts are successively connected to form a row, if both ends of resistance row are connected to a power supply voltage, the potential at the end of No.l resistance region is to be (power supply voltage)Xl/m. Furthermore, it will be feasible to provide mutually independent P type semiconductor region as well as N type resistance regions in the P type semiconductor regions reversing the P type and the N type further to form the resistance row wherein the potential in respectively independent P type semiconductor regions is connected to the low potential side of N type resistance regions in the P type semiconductor regions.

IPC: G06F12/08
Filed: 1994-12-06
Abstract: PURPOSE:To decide the time when the cached data are invalidated by the result of the data storing action of another processor. CONSTITUTION:A server stores plural data value, and a client stores the sub-sets of these data value in a cache.

Title: Method for treating shell
Inventor: TAMURA TERU
IPC: C01F11/04
Filed: 1990-11-09
Abstract: PURPOSE:To utilize shells which are industrial wastes and simply obtain calcium oxide by heating the shells at a relatively low temperature in an oxidizing atmosphere, burning and removing organic components, then igniting the resultant shells at a high temperature and converting the Ca component into Ca oxide. CONSTITUTION:Organic components are burned and removed by slowly heating shells such as scallop shell or oyster shell to 500-700 deg.C in an oxidizing atmosphere (at about 2-10 deg.C/min heating rate). The resultant shells are then ignited at >=800 deg.C and burned until a brittle state is attained. The obtained ignited shells are subsequently pulverized. If the amount of oxygen supplied is deficient or combustion time is insufficient in the combustion and removing stage of the organic components, impurities such as CaCO3 are mixed in the final product. The burning in the latter stage is continued until the shells are embrittled and a state in which the shape is collapsed simply by touching is attained. The Ca components in the shells are nearly completely converted into CaO by the aforementioned burning treatment. Thereby, the burned shells are pulverized to afford nearly pure CaO powder.

Title: Schmitt trigger circuit
Inventor: KURODA HIROYO
IPC: H03K3/027
Filed: 1988-11-30
Abstract: PURPOSE:To generate a Schmitt trigger at the output terminal of a latch circuit so as to facilitate the design of a circuit by inputting the outputs of two pieces of the buffers or the inverters of different switching levels to a NAND gate and an OR gate respectively, and inputting the outputs of those to the latch circuit. CONSTITUTION:When input voltage is increased gradually, since the outputs of the respective buffers 1, 2 are Low at the voltage below the switching level VT- of the buffer 2, the output of the NAND gate 3 becomes High, the output of the OR gate becomes Low, and the output of the latch circuit becomes High. The input voltage is increased further, and in the range of VT-<VIN<VT+, since the output of the buffer 2 is High, and output Vout of this circuit is left as it is High. When the input voltage is increased further, and it becomes over VT+, since both the outputs of the buffers 1, 2 become High, the output Vout of this circuit is turned into Low. As stated above, the switching levels VT+, VT- and the Schmitt width DELTAVT of the whole Schmitt circuit are determined by only the switching levels of the buffer or the inverter.

Title: Dc resonance converter
Inventor: OZU KIYOTSUGU
IPC: H02M3/335
Filed: 1993-11-09
Abstract: PURPOSE:To avoid an unstable operation caused by the decline of an operation frequency over a whole load range by a method wherein a frequency control is performed in a heavy load range and a PWM control is performed in a light load range. CONSTITUTION:When a load resistance 28 is small, a voltage is controlled by a frequency control performed by switching. A resonance current is made to flow by the on-off operations of main switching devices 11-14. The resonance current is carried by transformers 19 and 20 and converted into the secondary currents of the respective transformers 19 and 20 which are carried by the load resistance 28 as a common load current. If the load resistance 28 is increased, the switching operation frequency is declined. When the frequency becomes close to an audio frequency range, the control is switched to a PWM control. That is, while the resonance current is carried continuously, auxiliary switching devices 29-32 are turned on to apply the resonance current to the primary windings of the transformers 19 and 20 for required periods. As a result, the on-periods are controlled and the voltage control by PWM is performed.

Filed: 1989-11-22
Abstract: PURPOSE:To enable the circuit to code a fine analog signal into a binary signal for amplification by connecting first and second NOR circuits, which are respectively composed of field effect transistors, while being crossed, constituting the amplifier of two inputs and applying bias to the NOR circuit so that input sensitivity can be maximum. CONSTITUTION:The source electrodes of thin film transistors T2, T3, T5 and T6 are totally connected and this total connecting point is grounded through the drain and source of a thin film transistor T7 for bias supply. A control voltage Va is applied through a terminal 14 to the gate electrode of this thin film transistor T7.
